Abstract

                                The effect of application of growth retardants uke CLC, SADH, and morphactin along with othrel at two concentrations on fruiting and yield in pumpkin (Cucurbita Moschata Duch, ex Poir.). Selection-124), all the growth retardants at different stages induced the first fruit set at the lower nodes between 8.6 and 14.0, while ethrel treatment produced the fruit set between 3.3. and 4.3. Ethrel at 100 ppm at the initial stages proved to be the best treatment in increasing the number of fruits. Ethrol developed smaller size of fruits, which can commercially be exploited. The 2+4 leaf stage gave better yield with CCC 400 ppm and morphactin, while at 2- leaf and 2+4+6 leaf stage ethrel and SADH proved promising The increase in yield of 4.0 kg per vine is a spectacular increase in case of pumpkin, where fruit is carried to maturity on vine itself.
